MOUTH-PIECE GUARD FOR PHONOGRAPHS OR TELEPHONES.

SPECIFICATION forming part of Letters Patent No. 401,732, dated April23, 1889.

Application filed August 3, 1888. Serial No. 281,841. (No model.)

To aZZ whom it may concern:

3e it known that I, \VILLARD Ii. UANDEE, of Brooklyn, in the county ofKings and State of New York, have invented certain new and usefulImprovements in Guards for Mouth-Pieces or Sound-Conveying Tubes orChambers for Phonographs, &c., of which the following is aspecification.

The object of my invention is to provide improved means for preventingthe reverberatory or hollow muffled sound that occurs when words areuttered into a mouth-piece o1- sound conveying tube or chamber which isin too close proximity to the mouth.

The invention consists in providing a skeleton mouth-piece or guard inwhich there is opportunity for escape or circulation of the air agitatedby the voice to a sutlicient extent to preserve the natural tones of thevoice and prevent the objectionable quality of sound above mentioned,which in phonographic and telephonic apparatus materially interfereswith their perfect working.

Several forms in which my invention may be embodied are shown in theaccompanying drawings, in which Figures 1, 2, 3, l, and 5 arerespectively detail perspective views of mouth-pieces constructed inaccordance with my invention.

In Fig. 1 an ordinary mouth-piece, A, which may also be considered asrepresenting the ordinary sound-conveying tube or chamber of aphonograph or telephone, is provided with a circular wire guard, B,eitherpermanently or detachably connected therewith. The guard preventsthe too close approximation of the lips to the orifice and preserves thepurity and distinctness of the words spoken. The same result may beaccomplished by arranging wires B at right angles across the ordinarymouth-piece, as in Fig. 2. The wires are preferably curved and theirconvex faces turned outward; or, as shown in Fig. 3, the sides of theordinary mouth-piece may be cut away, as illustrated at a.

Fig. at illustrates a form of mouth-piece used with the graphophone. Itis relatively 1n neh larger than the other moutl1-pieces illustrated,and may be conformed to my invention by placing wires B across itsopening, or an arrangement similar to that shown in Fig. 2 might beused.

In Fig. 5 I have shown a semicircular guard, B applied to themouth-piece in a manner similar to that shown in Fig. 1.

The different figures serve merely to illustrate some of the forms inwhich my invention may be embodied.

Vith such guards better records are made upon the tablets or cylindersof graphophones and phonographs than with ordinary mouthpieces, and thenatural tones of the voice may be reproduced therefrom with distinctnessand without any diminution. of. the usual volu me of sound.

I claim as my invention-- 1. The combination of the mouth-piece orsound-conveying tube or chamber of aphonograph, telephone, or the like,and an openwork or skeleton guard arranged in front thereof,substantially as and for the purpose set forth.

2. The combination of the mouth-piece or sound-conveying tube or chamberof a telephone, phonograph, or the like, and a skeleton wire frame orguard arranged in front thereof, substantially as and for the purposeset forth.

In testimony whereof I have hereunto subscribed my name.
